D. Majumdar et al., ON THE TWISTED INTRAMOLECULAR CHARGE-TRANSFER EMISSION FROM THE 1ST EXCITED-STATE OF P-(N,N-DIMETHYLAMINO)BENZONITRILE, Journal of photochemistry and photobiology. A, Chemistry, 73(3), 1993, pp. 177-178
The possibility of twisted intramolecular charge transfer (TICT) emiss
ion of p-(NN-dimethylamino)benzonitrile (DMABN) triggered by stretchin
g of the -C=N bond has been explored. A detailed theoretical analysis
using semiempirical MNDO and CNDO/S-CI methods has been carried out to
examine this possibility. The results clearly show that -C=N stretchi
ng alone has little to do with the TICT phenomenon of DMABN.
